SHUT-OFF-ALVE-HAEIDLE 1,040,343. Application filed September '21, 1&0'3,Serial He. 518,8

To all whom it may concern:

Be it known that l, ROLLER B. Jorms rozv, a citizen of the United State,residing at Manchester, in the county of Hillslmro end State of NewHampshire, have invented a new and useful Shut-Oll-Va-lve-Hendie Sig naland Lock-Spring, of which the following is a specification.

My invention relates to shut-oil valves in stalled in metal pipes forthe conveyance of steam, water or other liquid, where it necessary ordesirable for convenience or safety that there be indicators showingclearly and instantly Whether the valves are open or closed end meansfor safely locking such indicators in o e-n position, but moreparticularly to an improvement in automatic sprinkler devices wherebythe or- (linary shut-oil". valve, of either the globe r gate" type,wellltnown to the trade, may with my invention attached, be in stalledand safely used to instantly close the low of water in any branch pipein or more of the sprinkler-heads the: come damaged by. accident orotherwise,

without stopping the flow in the other branches in the same section,floor, or build ing, and clearly indicate such closure.

I am not aware of any safety device in the various autoinntic sprinklerinventions in actual use, which limits the flow of Water in any onebranch or distributing pipe for needed repairs, except the main "hue-oilvalve for each floor, section, or build ng, as the case may be; andWhile-in several pet.- ents valve arms, handles, levers or indicatorsare shown, they are universall" with only one exception known to me,integral with or component parts of the sprinkler-heads, and in case ofaccident necessitating repairs to any head, the flow of water must bestopped at the main shut-oil until such re pairs are completed, as inNo. 346,796, Joseph Andrew, automatic fire extinguisher, patented Aug.3, 1886, and in No. 7 494, Fred M. Allen, automatic fire extinguisher,patented June 30, 1903; the one exception being the device shown inpatent to 'l homus, 570,689, Nov. 3, 1e90, (um--21) wi H clearlydistinguislmhlc from my invention principally in that the operating ltermed the lever, is pivotal at one ends to an object. independent ofthe and is limited to the special straight. plungenvulve therein shown.

ticle crnimercc, well known and in use for many years the combination ofsuch valve with c tly lengthened handle with outer end so broadened asto attract in tree, with a spring lock to securely hold the valve handlein open position, until inanposition, is entirely new and novel.

in :2 working model of my invention. 1 have chosen to paint. the broad,fiat hlade ol the handle white, lgut any color'niosi' notice able forany special installation could, of sour he used, as for instance, aphosphorus paint which would readily indicate the position of the handleby night as well as by day. 7 I

lhe nature of the invention is more fullv described below and isillustrated in the drawing filed in the Patent Office with my originalpapers, in which similar letters 6: reference indicate correspondingparts.

The lock-spring and its collar arell'lifi l'ill, preferably made of wrought steel and welded togellicr inorder to give this part. the greatest possible strength. The spring isformed from one ally forced out of the lock, and to closed by even acareless workman.
